Description

Technical Field

[0001] This utility model relates to the field of steering gear assembly technology, specifically a tooling for straightening steering gear tie rods. Background Technology

[0002] The steering system is an important component of a car, and the steering gear is the crucial connection between the steering wheel and the tires that enables steering.

[0003] The tie rod is a crucial component connecting the steering gear and the tires. For example... Figure 1 As shown, the tie rod consists of two parts: a mounting sleeve 2 and a tie rod body 1. One end of the tie rod body 1 is spherical and enclosed in the mounting sleeve 2, allowing the tie rod body 1 to rotate freely within a certain angle range. One end of the mounting sleeve 2 has threads for connection and assembly with the steering gear.

[0004] During the assembly of the tie rod and the steering gear, due to the inherent misalignment of the tie rod itself, there is a significant offset angle A between the tie rod body and the mounting sleeve. Figure 2 As shown. During the manual assembly of the tie rod, the offset angle A prevents the tie rod and the steering gear from engaging their threaded interfaces, thus preventing the assembly from being completed.

[0005] Therefore, it is necessary to design a tooling for straightening the tie rod of the steering gear to straighten the tie rod and ensure the angle between the tie rod body and the mounting sleeve to the greatest extent possible, so that the tie rod and the steering gear can be assembled with threaded interfaces. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tooling for straightening the tie rod of a steering gear. This tooling straightens the tie rod and maximizes the angle between the tie rod body and the mounting sleeve so that the tie rod and the steering gear can be assembled with threaded interfaces.

[0007] To achieve the above objectives, this utility model provides a tooling for straightening a steering gear tie rod, comprising a base plate, a limiting block, a handle, a straightening platform, and a horizontal block. One end of the top of the base plate has an upward-opening U-shaped limiting seat. One side of the U-shaped limiting seat has a mounting hole. The handle passes through the mounting hole and connects to the limiting block. The limiting block abuts against the plane of one side of the tie rod's mounting sleeve. The plane of the other side of the tie rod's mounting sleeve is flush with the inner wall of the U-shaped limiting seat. The top of the base plate also has a boss. A straightening platform is installed in the center of the boss. A connecting piece at the bottom of the straightening platform is threaded to the boss. A connecting rod is installed on the boss. One end of the horizontal block is mounted on the connecting rod, and the horizontal block is located directly above the straightening platform.

[0008] The distance between the U-shaped limiting seat and the boss is matched with the length of the horizontal tie rod.

[0009] The distance between the horizontal block and the straightening platform matches the outer diameter of the tie rod body.

[0010] The mounting sleeve for the tie rod has eight planes.

[0011] Compared with existing technologies, this invention uses a limiting block that cooperates with the U-shaped limiting seat on the base plate to achieve positioning of the eight planes of the mounting sleeve through four installation steps. The position of the limiting block can be adjusted via a handle to accommodate mounting sleeves of different sizes. A rotating straightening table adjusts the height and, in conjunction with a horizontal block, straightens the tie rod. This invention offers advantages such as simple operation, low precision requirements, rapid straightening, and applicability to all types of tie rods. Attached Figure Description

[0014] Figure 3 This is a schematic diagram of the structure of this utility model.

[0015] Figure 4 This is an exploded view of the present invention. Detailed Implementation

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] See Figure 3 and Figure 4 This utility model is a tooling for straightening the tie rod of a steering gear, including a base plate, a limiting block, a handle, a straightening platform, and a horizontal block. The top end of the base plate 3 has an upward-opening U-shaped limiting seat 31. One side of the U-shaped limiting seat 31 is provided with a mounting hole. After the handle 6 passes through the mounting hole, it is connected to the limiting block 7. The limiting block 7 abuts against the plane of one side of the mounting sleeve 2 of the tie rod. The plane of the other side of the mounting sleeve 2 of the tie rod is in contact with the inner wall of the U-shaped limiting seat 31. The top of the base plate 3 is also provided with a boss 32. A straightening platform 4 is installed in the center of the boss 32. The connecting piece at the bottom of the straightening platform 4 is threadedly connected to the boss 32. A connecting rod 33 is installed on the boss 32. One end of the horizontal block 5 is installed on the connecting rod 33, and the horizontal block 5 is located directly above the straightening platform 4.

[0018] To further meet the requirements of the tie rod, the distance between the U-shaped limiting seat 31 and the boss 32 is matched with the length of the tie rod. The distance between the horizontal block 5 and the straightening platform 4 is matched with the outer diameter of the tie rod body 1.

[0019] When this utility model is in operation, pulling the handle 6 leaves space for placing the horizontal tie rod. One plane of the mounting sleeve 2 fits against the side wall of the U-shaped limiting seat 31. Pushing the handle 6 causes the limiting block 7 to fit and clamp against the other plane of the mounting sleeve 2. Pressing the tie rod body 1 against the straightening table 4 causes the horizontal block 5 to contact the tie rod body 1. Rotating the straightening table 4 adjusts its height until the horizontal block 5 is in a horizontal position, thus obtaining a small offset angle A.

[0020] The tie rod mounting sleeve 2 has eight planes. By positioning the eight planes of the mounting sleeve 2 four times, that is, by using two planes for straightening each time, and repeating the straightening operation four times, the tie rod is straightened. After straightening, when assembling the tie rod with the steering gear, the thread of the mounting sleeve 2 mates with the threaded hole of the steering gear. The thread engagement is achieved by rotating the tie rod body 1, thus achieving the assembly purpose and improving assembly efficiency.

[0021] In this invention, the limiting block cooperates with the U-shaped limiting seat of the base plate, achieving positioning of the eight planes of the mounting sleeve through four installation steps. The position of the limiting block can be adjusted via a handle to accommodate mounting sleeves of different sizes. A rotating straightening table adjusts the height and, in conjunction with a horizontal block, straightens the tie rod. This invention offers advantages such as simple operation, low precision requirements, rapid straightening, and applicability to all types of tie rods.
